Hidden underground is a network that enables most green plants to survive. Without it, most green plants would be unable to survive. It’s a network of mycorrhizal fungi. In 1960, a Swedish botanist demonstrated that substances pass between plants through a fungal pathway. In the 1980s, it became clear that most plants form mycorrhizal associations. In a play on words from the “worldwide web,” English researcher David Reed called this underground network “the wood wide web.”
Through this network, plants exchange nitrogen, phosphorus, water, and carbon. These fungal networks collaborate by connecting with one another, forming a vast, complex mycorrhizal network. Although it is not worldwide, it can be wood wide.
An extreme example of a plant that depends on the wood wide web is Monotropa uniflora, also known as ghost pipes. They resemble white smoking pipes, with their stems stuck in the ground. They are white because they lack chlorophyll and therefore cannot use photosynthesis to produce the nutrients plants need. Since the fungal networks form physical connections between plants, allowing them to share nutrients, Monotropa plants freeload on other plants.
Although Monotropa is an extreme example of dependence on the wood wide web, most other plants depend on receiving and sharing the nutrients required for plant life. We normally think of plants as separate units, and we may even think of them as competing with one another, but that is not always the case. Sometimes tall plants, such as trees, compete with smaller plants by blocking sunlight. However, they may also share nutrients underground through the mycorrhizal network.
Only in recent years have scientists discovered the wood wide web, even though it has surely been around since God created plants. This fungal network is still not fully understood, but science is seeking to understand it. How many other things in God’s creation will we discover in the future? It is clear that we have much to learn about the vast web of life. “For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse” (Romans 1:20).
